TYPE-BAR CLIP FOB TYPIEWRITERS.

Application filed May 5,

To all whom it may concern Be it known that I, GEORGE J. ANsrEAn, a

citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Type-Bar Clips for Typewriters, of which the following a specification.

This invention relates to the type bars of typewriting machines, and its object is to provide the same with a novel and improved device for preventing wear thereof, as will be pointed out in thedetailed description appearing hereinafter.

In order that the invention may be better understood, reference is had to the accompanying drawing vherein Figure 1 is an elevation showing the application of the invention; Fig. 2 is an enlarged cross-section on the line 22 of Fig. 1; Fig. 3 is a perspective view of one of the type bars, and F i is a perspective view of the wear device detached from the type bar.

In the drawing, 5 denotes the segment which is provided with slots for the reception of the pivoted ends of the type bars, one of which latter is shown. at 7 in l and 3. The segment also carries a bracket 8 provided with the usual center guide for the type bars, said guide being composed of two laterally spaced fingers 9 between which the type bars enter at the. end of their working strokes. The parts thus far described con stitute the type bar support and guide of an ordinary front-strike typewriting*machine, and as nothing is claimed with respect thereto, a further description. thereof is not neces sary.

That portion of the type bar which goes between the fingers 9 is subject'to rapid. wear at its sides from frequent contact with the 1922. Serial No. 558,615.

inner or guide surfaces of the fingers. This wear causes the alinement to get load, which, of course, makes neat work impossible. In automatic machines, owing to the high speed at which the machines operate and the con. stant demands made thereon, the wear of the type bars is very rapid, and the life of a type bar is'comparatively short. I. have therefore provided type bars with areinforcement consisting of a plate or strip 10 of case-hardened steel or other suitable hard metal, which is bent into U-shapeso that it may be slipped over the type bar from the rear edge thereof, and fit the sides thereof, as clearly shown in Fig. 2. This reinforcing or wear member may be soldered, welded or otherwise rigidly attached. to the type bar, and as it is positioned to come between the guide fingers 9 on the working strokes of the type bar, and keepsthe same from coming in. contact with the guide fingers, it takes all wear off the type bar.

The device can be readily applied, andby its use the expense of replacing worn type bars entirely eliminated. The device is also very inexpensive, and its first cost is practically the only expense, and this is even less than the cost of just one set of new type bars. The device can also be made to fit the type bars of all standard makes of machines.

I claim:

A. type bar for typewriting machines having its portion which enters the center guide of the machine provided wit-h a wear plate, said plate fitting the sides of the type bar for keeping the same out of contact with the guide.

In testimony whereof I ailix my signature.

GEORGE J. ANSTEAD.
